GARBAGE-DISPOSAL DEVICE.

Application filed November 24, 1920. Serial No. 426,303.

To all whom it may concern Be it known that I, DOMINICK RODGERS, a citizen of the United States of America, residing at Pittsburgh in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Garbage-Disposal Devices, of which the following is a specification.

The present invention relates to garbage disposal devices, and provides a means of grinding into fairly small sized pieces the kitchen refuse such as vegetables, meat, bones, so that such material will then readily pass through a medium sized pipe and readily conveyed to a public sewer, to a garbage can, or other place or means of disposal such as an incinerator. By using my invention a very cleanly and convenient means of handling garbage without going out of doors is provided, which is especially desirable in cold or inclement weather, and as the dis posal means is at hand, the refuse is at once removed from the vicinity of the kitchen which is also a desideratum, which can at once be appreciated. These and other features of the device will be elaborated upon and thoroughly explained as the description proceeds.

In the accompanying drawings forming part of this specification I have shown a complete embodiment of my invention.

Figure 1 is a central vertical section of my invention.

Figure 2 is a horizontal section on lin 22 of Figure 1.

Figure 3 is a horizontal section on line- 33 of Figure 1.

Figure 4 is a horizontal section on line 4-4of Figure 1.

Figure 5 is a partial enlarged vertical section of. details shown in Figure 1.

Figure 6 is a horizontal section on line 6-6 of Figure 5.

Figure 7 is a plan view of the cutter used in the device.

Figure 8 is a fragmentary elevation on line 8-8 of Figure 5 showing a feature of a special casting used.

The numeral 1 indicates an ordinary kitchen sink provided as usual with the drain disc-plate 2, to which is attached the funnel 3, and thepipe 4 carries the casting 5 which connects the upper portion of pipe 4 with the lower section 6 of the same.

The casting 5 has a circular horizontal chamber '7 adapated to accommodate the bevel gear 8, the latter being rigidly mounted on the periphery of the worm or screw 9. The worm 9 revolves freely in the pipe 4, and is supported by the perforated discplate 10, the latter being supported by screws at 11, 11 in the walls of pipe 4. The worm 9 has a pintle 12 on the lower end thereof on which is the cutter 13, the latter being rigidly mounted against rotation by means of the screw 28 which is in engagement with a complementary recess in the pintle 12. The cutter 13 is provided with blades 14, 14 which are sharpened at the bottom 15, 15, to a knife or cutting edge and preferably curved somewhat as shown in Figures 5 and 7, so that as the cutter revolves the blades 14, 14, shear the garbage passing through the grooves of the worm 9 against the perforated disc-plate 10. The disc-plate 10, has a plurality of perforations 16, 16, etc. through which the garbage passes into the larger or enclosing pipe 17 and thence is conveyed to the place of disposal such as av sewer, incinerator, garbage can or the like.

The casting 5 has a lower cap 18 which is attached to the upper portion 19 of said casting for assembling and repairing purposes. The portions of the cap 18 and part 19 are cut away at 20, 21 respectively to permit the gears 8 and 22 to operate. The lat ter gear 22 is mounted in the boss 23 formed on the pipe 17, and is provided with a handle 24, screw-threaded on stem 25' of the gear 22. It is evident that when handle 24 is actuated that the worm 9 is at once revolved and any refuse in the grooves of the worm is forced down through the blades of the cutter 13 where it is sheared by blades 14, 14 and thence passes through the perforations of the disc-plate 10, and into pipe 17 to the place of disposal.

The refuse is placed in funnel 3 by removing the plate or drainer 2, and the movementof garbage through the worm 9 and pipe 4 is facilitated by permitting the Water to flow down upon said garbage in tube or pipe 4, and any excess of water can flow through the perforations 26, 26 in the funnel 3 and thus to pipe 17. A portion 27 of. the pipe 17 is removable immediately around the boss 23 so that access may be had to the bevel gears 8 and 22 and associated parts when necessary repairs are needed, or the de- '-vice is being assembled for service.

From which description it is seen that I convenient for the purpose readily operable.

manually and which avoids the necessity of the housewife or servant leaving the house in cold or inclement Weather. By the convenient location of the device, and its ready operation the use of pans holding the garbage in the kitchen temporarily 1s entirely eliminated, and the unsightly garbage is disposed of at once.

The Whole device is readily cleansed by the use of hot Water from the spigots with which the sink is ordinarily provided.

I claim:

1. In a garbage disposal device, an inner pipe, a worm revolubly mounted in said pipe, a gear on the worm, a cutter on the base of the Worm, a disc-plate in adjacent shearing relation with said cutter, an outer pipe, and means mounted on the outer pipe for actuating the aforesaid gear to operate the worm and cutter.

2. In a garbage disposal device, an inner pipe, a worm revolublymounted in said inner pipe, a horizontal bevel gear on the periphery of said worm, means for connecting the inner pipe' in proximate relation to the drain hole of a sink, a cutter on the base of the worm, a perforated disc-plate in adjacent shearing relation to saidvcutter; an outer pipe, a vertical bevel gear mounted on the outer pipe, in engagement With the firstmentioned gear, and means for revolving the vertical gear to operate the cutter in proximity to the disc-plate.

3. In a garbage disposal device, a pipe having an upper and a lower section, a worm revolubly mounted therein, a horizontal bevel gear on said worm, a casting uniting the pipe sections, having a chamber therein adapted to accommodate the horizontal gear, a cutter on the worm, a perforated discplate mounted in the said pipe in proximate shearing relation to said cutter and means for actuating said horizontal gear to revolve the Worm'and cutter.

4. In a garbage disposal device, an inner pipe having an upper and a lower section, a worm revolubly mounted in said pipe, a horizontal gear on the worm, a casting uniting the pipe sections, having a chamber adapted to accommodate the horizontal gear. a cutter on the worm, a disc-platein proximate shearing relation to the cutter, an outer pipe, a vertical gear in meshed engagement with the horizontal gear, mounted in the wall of the outer pipe, and means for actuating said vertical gear to operate the worm and cutter.

5. In a garbage disposal device, an inner pipe having an upper and a lower section, a worm within the pipe, a horizontal gear on the worm, a casting uniting the pipe sections having a chamber adapted to accommodate the horizontal gear, means for pulverizing refuse contained in the worm grooves, an outer pipe, a vertical gear carried by the outer pipe and adapted to revolve the horizontal gear, when the vertical gear is properly actuated.

6. In a garbage disposal device, a pipe having an upper and a lower section, a worm revolubly mounted therein, a horizontal gear on the worm, a casting uniting the pipe sections adapted to accommodate the horizontal gear, refuse grinding means within the enclosing pipe, and means for actuating the horizontal ear to revolve the Worm, and aforesaid grlnding means.

In testimony whereof I aflix my signature.
